How is a PSMA expression measured? I know there is a scoring range used 0 - 3, zero being no and 3 being high.

@stew80 Some centers normalize the SUVmax range to 0-3. I’ve seen some report SUVmax scores in the double-digits. I know one guy who had an SUVmax of 18.7; that was within the range that center chose to use.
Kind of like with PSA scores - some labs go to 1 significant digit, some to 2 significant digits, others to 3 significant digits. All are right; it just depends on what range they choose to use.

@stew80 Not sure about scoring range, but the background uptake in the prostate is SUV 2.1, and the uptake in the known lesion (PI RADS 5 lesion revealed by MRI and confirmed by biopsy) is only SUV 2.3. As a result, radiology report states "no marked prostate gland activity definitive for malignant neoplasia".
